For circular areas you only need one measurement, the distance across the circle, or diameter (as shown in the
image at the right). The formula then is:Area = (Diameter / 2)2 x 3.14

Diameter in Feet

Total Square Feet

Oval Areas / Square Footage

Oval areas need measurements similar to a rectangle. Simply take the length from one end to the other,
and the width at the widest point. The formula you need then is:Area = 0.8 x Width x Length

Length In Feet

Width In Feet

Total Square Feet

Triangle Areas / Square Footage

Triangles are another fairly simple shape. As illustrated at the right it's simply a matter of taking the
height at the tallest point and the width at the base of the triangle and then multiplying those by half. So in this
case the formula you need is:Area = 0.5 x Width x Height

Height In Feet

Width In Feet
